Genetic divergence studies in foxtail millet [Setaria italica (L.) Beauv.]
Fifty genotypes of foxtail millet were subjected to multivariate analysis through Mahalanobis’ D2 statistics (Tocher’s method) and Wards’ minimum variance method. Both D2 analysis and Ward’s method grouped the 50 foxtail millet genotypes into eight clusters each. However, the clusters are different...
